Application filed February to, 1928. Serial No; 255,794.

lhis invention relates to improvements in beaters or mixers of that type adapted to be manually operated for effectively heating or mixing one or more materials contained in a receptacle.

The primary object of the present invention is to provide a beater which is extremely simple and durable in construction and which embodies parts which may be economically manufactured and readily assembled to insure the production of a uniformly desirable and efficient product or heater.

A further object is to provide an improved connection between the legs of the supporting loop for the beater blades and the legs of the handle carrying supporting frame for the driving gear. 7

A still further object is to provide improved means for effectively preventing separation or spreading of the legs of the loop and frame so that maintenance or the drivin pinions for the beater blades in mesh with the driving gear is most positively insured, such means also effectively preventing movement of the legs toward each other so that binding of the rotatable parts is most eifectively prevented.

Another object is to provide for the operative positioning of the spur pinions in overlapping planes whereby riding of one pinion upon the other is prevented and elitetive engagement of both pinions with a flat driving gear is attained and insured.

Still another object is to provide a beater composed of parts so designed and connected as to entirely avoid the use of sepa rate securing elements such as screws, rivets and the like.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In thedrawing:

Figure 1 is an elevational view of a beater embodying the present invention;

Figure 2 is a fragmentary side elevational view showing the portion of the beateradj acent the driving gear and spur pinion, as seen looking toward the right of Figure 1;

Figure 3 is an enlarged horizontal section on line 3--3 of Figure 1;

Figure 4 is a perspective view of the pinion guard and leg bracing elements; and

Figure 5 is a fragmentary perspective view, partly broken away of the driving gear supporting frame.

Referring more in detail to the drawing the present type of beater embodies two adjacently disposedpairs of beater blades 5 andG having outwardly curved lower operative end portions and rotatably mounted at their upper and lower ends on the legs 7 of a U-shaped supporting loop 8, a spur pinion 9 being fixed upon the upper end of each pair of beater blades ina substantially horizontal position and adapted to mesh with a vertically disposed driving gear 10 mounted between the spaced legs ,11 of a frame carrying a handle 12 at theupper end thereof and having the lower ends of its legs 11 connected to the upper endsof the legs 7 of the loop 8. The driving gear 10 is carried by a suitable horizontal shaft 13 mounted in the legs 11 and equipped with a suitable operating handle 14 at one end.

In accordance with the present invention the upper ends of the beater blades 6 are disposed slightly higher than those of the blades 5 so that the spur pinions 9 are disposed in different horizontal planes and overlapped at their inner sides in slightly spaced relation for simultaneous engagement with the driving gear 10, which is of the flat type or provided with a single set or circular series ofteeth. By reason of this construction, a most simple and ineXpensive term of driving gear can be employed, and effective driving engagement of the pinions 9 with the gear 10 is insured Without liabil ity of the pinions riding one upon another so as to cause binding or unevenness of action.

The present invention also embodies the provision of improved means for rigidly connecting the adjacent ends of the legs 7 and 11 and for effectively bracing them against separation or movement toward each other such as mightcause binding of the gearing parts or destruction of effective driving connection 'therebetween. For this purpose the lower ends of the legs 11 have the side portions thereof directed laterally in the form of outwardly projecting normally parallel flanges 15 to form sockets open at the outer sides to permit lateral into the wings 19 to provide clearance for the driving gear where meshes with the pinions 9. The plate .18 also has tongues 20 stuck upwardly and outwardly therefrom at opposite sides of the 19 centrally of the plate 18, so to form a further slot 21 intersectin and disposed at right angles to the slot is, the tongues 20 projectin upwardly from the plate 18 at the ends or the slot 21. The upper end portions of the legs 1 of the loop 8 are passed upwardly through the slots 21 and disposed against the innersides of the to; gues 20, the latter being positioned in the sockets formed by the flanges 15, and the plate 18 being disposed to abut the lower ends of the flanges 15. The free vertical edges of the flanges are then bent together and clinched about the tongues and the adjacent portions of the legs 7 as indicated at 22, thereby firmly and ri idly connecting the parts .vithout the use of separate fastening means. In this way, the supporting loop 8 for the beater blade and the handle carrying supporting frame for the (ilriving gear 10 are most durably and rigidly connected, and the pinion guard and bracing element is also lirmly secured in place so that absolutely no freedom. of movement is allowed between the respective legs of the loop 8 and the frame and consequently binding or disengagement of the gearing parts is etlectively prevented. The engagement of the extensions in the openings 17 effectively prevent relative longituoinal displacement of the loop 8 and the driving gear support ing frame, thereby holding the pinions 9 against the underside of the plate 18 and firmly binding it against the lower ends of the sockets partially formed by the flanges 15. Obviously, this avoids any play what ever of the tongues 20 in the closed sockets formed by in ing the free edges of the flanges 15. Moreover, the opposite end portions of the plate 18 are offset in different horizontal planes to overlie and substantially cover the pinions 9 so as to act as guards therefor which are effectively braced andv connected by portions of the tongues 19 at both sides of the plate 18. The openings 23 in the legs 11 are those in w rich the shaft 13 of the driving gear 10 is journaled.

It will be noted that the supporting frame for the driving gear consists of two similar strips of strap metal having contiguous upper end portions .24 riveted or welded to gether and terminating in their upper ends in tangs suitably fastened in the handle 12. In other words, the handle 12 is suitably fa'jtened-on the tangs provided on the upper ends of the strip members whose lower end portions are of slightly dilferent lengths and spread apart in spaced parallel relation to form the legs 11 of different lengths as shown clearly in Figure 1.

it is obvious from the foregoing that the various parts can be readily stamped and assembled so as to insure uniform quantity product-ion in which each beater or article.

is extremely ligl'it in weight, unusually dur able in construction and effective in operation.
